. The frequency is lowered, as expected for increased masses. 12 C16O and
, we get ̃ 11. Oscillator. Compute the relative populations of the five lowest vibrational states of iodine, 127I2, at
thermal equilibrium at 15.0 ºC. The force constant for is 170 N m-1. (Set the relative population of the
ground state to 1).
The energies are
( ) ( )√ The thermal-equilibrium (Boltzmann) populations are given by
( ) With
, the values for
are n0 = 1.000, n1 = 0.345, n2 = 0.119, n3 = 0.0410 and n4 =
0.0142. This means that several vibrational levels are substantially populated...
